In this Wednesday, Feb. 6, 2013, file photo, snowboarders and skiers rest after competitions, in Rosa Khutor, some 60 km east of the Black Sea resort of Sochi, Russia.

Palm trees evoke a tropical seaside resort, but the Black Sea itself is seriously cold; turn away from the palms and the jagged, snow-covered peaks of the Caucasus Mountains rise nearby.
